英国科学家最近研究成功用真菌防治蚜虫的方法,为生物防治蚜虫开辟了新途径。具体方法是,向有蚜虫的植株喷洒真菌孢子,喷出的孢子能牢牢地粘着在植株上,并可存活好长时间。几天后,孢子发育成熟并产生小菌株。小菌株覆盖到蚜虫表皮上,吸取蚜虫的营养,蚜虫不久便死去。用真菌防治蚜虫的优点很多,操作简单,安全可靠,不会污染环境,费用较低,杀虫效果好。即使是深藏在植株叶片下面和不易喷洒到的地方,蚜虫也难以辜存下来。而且真菌具有传染病菌的本领,所以只要在某一块田里喷洒真菌孢子,不出几天就能使 British scientists recently studied the successful prevention and treatment of aphids with fungi and opened up new avenues for biological control of aphids. The specific method is to spray the fungus spores with the aphids on the plants, and the spores can be firmly adhered to the plants and can survive for a long time. After a few days, the spores matured and produced small strains. Small strains cover the aphids epidermis, drawing aphids nutrition, aphids soon died. Aphids with fungi control a lot of advantages, simple, safe, reliable, will not pollute the environment, lower costs, insecticidal effect. Aphids are hard to survive even if they are hidden under the foliage of plants and are not easily sprayable. And fungi have the ability to spread germs, so as long as the spraying of fungal spores in a field, within a few days can make
